Definitions

  • the invention relates to a short inking unit according to the preamble of claim 1.
  • Short inking units for offset web-fed rotary printing presses have become known for so-called anilox offset web-fed rotary printing presses.
  • Such an inking unit shows e.g. B. EP-0 278 225 A2.
  • This offset web-fed rotary printing press has two inking units at the bottom and one at the top. The type of arrangement of the cylinders, chambered doctor blades and dampening units of the lower inking unit is different from that of the upper inking unit.
  • the dampening system is on the outside.
  • a disadvantage of this inking unit is that the dampening system severely hinders access to the plate cylinder and that a chamber doctor blade cooperating on the side of the screen cylinder must be used.
  • the invention has for its object to provide an overhead short inking unit for an offset web-fed rotary printing press, in which the accessibility to the plate cylinder is well guaranteed.
  • the advantages which can be achieved with the invention consist in particular in that the accessibility of the overhead short inking unit is very good despite the fewer cylinders and a "normal" dampening unit to the plate cylinder.
  • the inking unit is also easily accessible to change the ink with a change of the doctor blade.
  • the offset printing unit 1 shown as an application example for a web-fed rotary printing press is a so-called satellite printing unit. It consists of two underlying (left and right) inking units in short form (short inking unit) 2 and 3, two overhead short inking units, i.e. H. a left 4 and right 6 and a central blanket-covered impression cylinder 7.
  • Each of the short inking units 2, 3, 4 and 6 consists of at least one chamber doctor blade 8, at least one printing ink supply and discharge device 9, a screen cylinder 11, an inking cylinder 12, a plate cylinder 13 with an offset printing plate, a dampening unit 14 which moistens the printing plate, and a blanket cylinder 16.
  • the blanket cylinders 16 are arranged on the impression cylinder 7 individually on and off.
  • the contact points 17 of the impression cylinder 7 with the blanket cylinders 16 each form a pressure point for a paper web 15.
  • Each of the dampening units 14 can be designed as a brush, spray centrifugal dampening unit, but also of another type.
  • Brush dampening systems are shown in the exemplary embodiment. They consist of a dampening water tank 18, a chrome-coated scoop roller 19, a brush roller 20, a chrome roller 21, a rubber-coated, first intermediate roller 22, a second intermediate roller 23 with an oleophilic surface, and a rubber-coated dampening roller 24, which applies an emulsion of the ink and fountain solution to the printing plate.
  • the dampening units 14 are located "inside", ie. H. hidden by the cylinders 12, 13, 16 seen from the operating sides 26 and 27.
  • doctor blade 8 is arranged so that its doctor blades are in contact with the "lower part" of the circumference of the raster cylinder 12.
  • the centers of rotation of the raster cylinder 11 and the inking cylinder 12 lie on a first plane 29 passing through them. It intersects a vertical plane 31 each passing through the axis of rotation of the blanket cylinder 13 at an angle ⁇ between 30 ° and 60 ° o .
  • the planes 29 and 32 intersect in the axis of rotation of the inking cylinder 12.
